Gauge Calibration: Both zero and span adjustments are available. This gauge has been configured with a default password of ØØØØØ. This factory password does not allow access to calibration. To access the calibration mode, it is necessary to configure a user password. Once the user password is configured, it will become the default password that allows access to gauge calibration.

To access the factory default password:

1. Step 1: Press the CONFIG key until the word CALIBRAT appears.

2. Step 2: Press the ENTER key.

3. Step 3: The letters/asterisks… PW***** appear.

4. Step 4: Press the CONFIG key. An Ø appears in the first position.

5. Step 5: Press the ENTER key once.

6. Step 6: Press the CONFIG key until Ø appears. Ø will appear in the second position.

7. Step 7: Press ENTER.

8. Step 8: Use this format until all the asterisks are replaced with Ø.
   There now should be a total of five Ø’s on the keyboard display. The zero in the fifth position should be blinking.

9. Step 9: Press the ENTER key. You are now prompted to SET PW (or set password).

10. Step 10: Press the ENTER key.

11. Step 11: Decide on a five number user password, then follow the procedure above inserting a number in the flashing display until all five numbers are inserted.

12. Step 12: A SAVE prompt will then appear. If the selected user password is acceptable, press ENTER. If the selected user password is not acceptable press ZERO CLEAR to refigure the user password.
    After the password is configured, the default factory password will be replaced with the user password. Once configured, the factory password is no longer accessible.
    If an incorrect password is entered, the system will display WRONG. Press the CONFIG key to reenter the correct password.

13. Step 13: Press ENTER again to begin calibration.
    Note: Calibration feature allows recalibration of zero and span.
    Zero Calibration:

14. Step 14: Press the CONFIG key once and the word CALIBRA appears. Press ENTER. (This mode allows for 0 and full- scale adjustment of span.) The gauge will now display 0.00. Ensure the gauge is not pressurized, 1 then press ENTER to zero the gauge. Zero calibration is now complete.
    Full Scale Calibration

15. Step 15: The gauge will now display full-scale range (e.g. 100.00 psi). Pressurize the gauge to 100% of the range (which is equal to the displayed value) utilizing a pressure standard with accuracy four times greater than the unit being calibrated. 2 Press ENTER. Full-scale calibration is now complete.

Notes:

1. If the digital gauge under test is not pressurized while in span adjustment of full-scale range, an ERROR message will be displayed when the ENTER button is pressed. If this occurs, press the ZERO CLEAR button on the keypad to return to the previous screen.
2. ASME B40.7-1998, section 6.1.1.1 recommends the working standard for the gauge being tested is 4X better than the digital gauge under test. This means the pressure standard measuring the full-scale pressure being applied to the gauge should have an accuracy four times greater than the unit being spanned.

Zero SP (span):
This feature allows setting the % of span in which the zero button will operate. Span is limited to prevent accidental tare of process pressures. Options are 5%, 10% or DISAB (5% is the factory default and means the unit can be rezeroed between ±5% of span). If DISAB is selected, the zero button is deactivated and no display change will occur when the zero button is pushed.

1. Step 1: Press the CONFIG key until the word ZERO SP appears.
2. Step 2: Press ENTER.
3. Step 3: Enter user five digit password (PW). This is the same password established to access the CONFIG mode in the menu.
4. Step 4: Press the CONFIG key to select the desired option.
5. Step 5: Press ENTER to finalize the selection.

Notes:
Selecting the DISAB feature does not disable the CLEAR button on the keypad for the MAX/MIN feature. If the DISAB feature is selected, pressing the ZERO button on the keypad will cause the display to read DISAB for two seconds. The gauge will then revert back to the unit of measure of the gauge. The DISAB feature disables the zero feature of the gauge.

Zero Disable Feature:
This feature allows disabling the Zero/Clear button on the keypad. It also allows for a zero tolerance of either 5% (default) or 10% of the gauge range.

1. Step 1: Press the CONFIG key until the word ZERO SP appears.
2. Step 2: Press ENTER.
3. Step 3: A prompt appears to enter PW (enter password). The ZERO SP password is the same password as discussed on page 10 and the heading CALIBRAT:, Gauge Calibration. Follow the instructions on page 10 to enter a password.
4. Step 4: Press the CONFIG key to select the zero tolerance, either 5% or 10% of range, or press the CONFIG key again and the word DISAB appears. Press ENTER to select the new default setting

If the user password is lost or stolen, contact Ashcroft Inc., customer service at (203) 378- 8281 for a new factory password that will allow the user to establish a new user password. DISABLE: allows “lockout” of individual CONFIG options. The default is ENABLE for all options in the CONFIG mode.

1. Step 1: Press the CONFIG key until the word DISABLE appears.

2. Step 2: Press the ENTER key.

3. Step 3: Insert the user password following the procedure as described in steps 3 through 13 above.
   Note: This is the same user password as in the CALIBRAT mode.

4. Step 4: Press the ENTER key.

5. Step 5: The first option in the CONFIG menu will now be displayed (UNITS).

6. Step 6: To DISABLE the UNITS option press the ENTER key until the word DISABLE appears.

Gauge Installation

Pipe Mount – The Ashcroft digital test gauge comes standard with a 1 ⁄4 NPT connection. Good piping practices recommend using teflon tape or a pipe sealant on the gauge threads. Utilize a 7 ⁄16˝ wrench on the wrench flat of the gauge to tighten the gauge to the process.

NEVER TIGHTEN GAUGE THREADS BY HOLDING THE BODY OF THE GAUGE. DOING SO MAY DAMAGE THE GAUGE AND MAKE THE GAUGE INOPERABLE.

Panel Mount – The lower connected Ashcroft digital test gauge is available with an optional flange for panel mounting. Please refer to illustration and dimensions below.

Battery Installation and Replacement

The gauge comes standard with three AAA alkaline batteries installed.
For battery replacement use only one of the three types listed below:

• Energizer AAA alkaline, E92 LR03 AM4 1.5V
• Energizer AAA alkaline, EN92 LR03 AM4 1.5V
• Duracell AAA alkaline, MN2400 LR03 1.5V

Do not mix ages or brands of batteries. Do not replace batteries in hazardous areas.

Batteries have a life of approximately 1000 hours. Battery life is dependent on gauge usage, backlite settings and power off settings. When the display flashes LOW BAT, batteries should be replaced.

To replace the batteries:

1. Remove the single screw on the back of the gauge case.
2. Hold the keypad in the palm of hand.
3. Carefully remove the three batteries from the holder and replace the batteries. Use only AAA alkaline non-rechargeable batteries.
